An aircraft with very bright green lights plummeted out of the sky then flew unexplainable speeds back into the night sky.

We were driving I-90 W at about 11:11 pm.

Witness # one's perspective: a white light approximately 6,000 ft appeared stationary Then accelerated to speeds that were unexplainable and disappeared. Upon acceration the light turned to two green lights on an oval shape craft.

Witness #2: An oval shaped craft with green lights appeared to plummet spinning towards the ground at an alarming rate of speed. At first it was thought to be an airplane that was going down but then it picked up to such speeds it was unimaginable and disappeared in the the night sky.
